- Purpose: To present the occurrence of metastases and local recurrences in primary non-metastatic patients with renal cell carcinoma (RCC) in a contemporary Swedish population-based cohort.Methods: Between 2005 and 2009, a total of 4527 patients were included in the prospective National Swedish Kidney Cancer Register accounting for nearly all RCC patients in Sweden. Among M0 patients, 472 (13 %) had no follow-up data registered within 5-year follow-up time and were excluded from the analysis.Results: In total, 939 (21 %) had distant metastases at presentation with a decrease from 23 to 18 % during the inclusion period. Of 3107 patients with follow-up data and with M0 disease, 623 (20 %) were diagnosed with a tumor recurrence during 5-year follow-up. Mean time to recurrence was 24 months (SD ± 20 months). Among these, 570 patients (92 %) were at primary diagnosis treated with radical nephrectomy, 23 patients (3.7 %) with partial nephrectomy and 12 patients (1.9 %) with minimally invasive treatments. The most frequent sites of metastases were lung (54 %), lymph nodes (22 %) and bone (20 %). The treatment of recurrence was in 50 % systemic treatments, while metastasectomy was performed in 17 % of the patients, out of which 68 % were with a curative intention.Conclusions: In this population-based study, 21 % of the patients had metastatic disease at presentation, with a decreasing trend over the study period. During 5-year follow-up, 20 % of the primary non-metastatic patients had recurrent disease. Of the patients with recurrence, half were given systemic oncological treatment and 17 % underwent metastasectomy.

Journal article (peer-reviewed)abstract
- Methodology: Since the start in 2005 virtually all patients with newly diagnosed renal cell carcinoma (RCC) in Sweden are reported to the National Swedish Kidney Cancer Register (NSKCR). The register contains information on histopathology, nuclear grade, clinical stage, preoperative work-up, treatment, recurrence, and survival.Results: A total of 8556 patients with newly diagnosed RCC were registered in the NSKCR from 2005 to 2013 resulting in a coverage of 99% as compared to the Swedish Cancer Registry. The mean tumor size at detection decreased from 70 mm in 2005 to 64 mm in 2010. The proportion of patients who were incidentally detected increased. The proportion of patients with tumor stage T1a who underwent partial nephrectomy increased from 22% in 2005 to 56% in 2012. Similarly, the proportion of laparoscopically performed radical nephrectomies increased from 6% in 2005 to 17% in 2010. During the five years of follow-up 20% of the patients had a recurrence.Conclusion: Over the last decade there has been a trend of earlier detection and less advanced tumors at detection in patients with RCC. An increasing proportion of the patients undergo laparoscopic and nephron-sparing procedures.

Journal article (peer-reviewed)abstract
- Objective: The aim of this population-based study was to evaluate the impact of quality indicators on the adherence to guidelines for renal cell carcinoma (RCC).Material and methods: Since 2005, virtually all patients with newly diagnosed RCC in Sweden have been registered in the National Swedish Kidney Cancer Register (NSKCR). The register contains information on histopathology, nuclear grade, clinical stage, preoperative work-up, treatment, recurrence and survival. In addition, a number of quality indicators have been measured in the register aiming to increase the quality of care. The quality indicators are: the coverage of the register, histology reports, preoperative chest computed tomography (CT), partial nephrectomy, laparoscopic surgery, centralization to high-volume hospitals and waiting times.Results: A total of 8556 patients with diagnosed RCC were registered from 2005 to 2013 (99% coverage). In 2013, 99% of the histopathology reports were standardized. The number of patients with preoperatively chest CT increased from 59% in 2005 to 89% in 2013. The proportion of patients with RCC T1aN0M0 who underwent partial nephrectomy increased from 22% in 2005 to 56% in 2013. Similarly, laparoscopic radical nephrectomies increased from 6% in 2005 to 24% in 2013. The median tumour size at detection decreased from 60 mm in 2005 to 55 mm in 2013. The proportion of patients who were incidentally detected increased from 43% in 2005 to 55% in 2013.Conclusions: The data show an improved adherence to the guidelines for RCC as measured by quality indicators and a steady process of earlier detection of patients with RCC.
